Пошаговое объяснение:
1)
81 = 3 * 3 * 3 * 3
12 = 2 * 2 * 3
НОК (81; 12) = 3 * 3 * 3 * 3 * 2 * 2 = 324
2)
42 = 2 * 3 * 7
48 = 2 * 2 * 2 * 2 * 3
НОК (42; 48) = 2 * 2 * 2 * 2 * 3 * 7 = 336
3)
16 = 2 * 2 * 2 * 2
НОК (16; 48) = 2 * 2 * 2 * 2 * 3 = 48
4)
101 = 101
21 = 3 * 7
НОК (101; 21) = 101 * 3 * 7 = 2121
